A handle for hand-tapping acrylic. It holds very well, it should work for tapping metal as well but I haven't tried it. Designed for my M6 tap ("WALTER METRIC 6.0MM TAPER HS TAP - 03-D061") from HD supply but fits the other ones I have around too.
If you need a case for your tap see http://www.thingiverse.com/thing:5670 - at some point I may try to merge these into one object.
Cut out attached file on laser cutter. Stack with circular hole on one side, no hole on the other and all three square holes in the middle. Solvent weld or otherwise stick layers together. Tap should fit in tightly, I wiggle it side to side to get it back out afterwards.
